Environment

Temperature

40 ºC - for wall mounting installation

50 ºC - for motor mounting installation using self-ventilation

2% of current derating for each ºC above the speciﬁc operating temperature, limited to an increase of 10 ºC

Humidity 5% to 95% non-condensing

Altitude

Up to 1,000 m - rated conditions

1,000 m to 4,000 m - 1% of current derating for each 100 m above 1,000 m of altitude

Protection degree IP66/NEMA 4X (the disconnect switch is IP65)

Performance

V/f control

Speed regulation: 1% of the rated speed (with slip compensation)

Speed variation range: 1:20

Vector control (VVW)

Speed regulation: 1% of the rated speed

Speed variation range: 1:30

Braking methods

DC current applied to motor

dynamic braking

Available as standard for frame size B. For frame size A “DB” models has to be used.

An extra resistor must be ﬁtted in for dynamic braking capability

Safety Protection

Overcurrent/phase-phase short circuit in the output

Overcurrent/phase-ground short circuit in the output

Under/overvoltage

Overtemperature in the heatsink

Overload in the motor

Overload in the power module (IGBTs)

External alarm / fault
